s t fi l This invention relates to-lip rousing devices, and the like, and aims generally to improve the same.

Lipsticks as conventionally supplied generally comprise some sort of holder from the end of which, during use, a rod or bar of limticlx paste projects for a considerable distance. As usually supplied the projecting end of the bar of lipstick paste is initially shaped at the tip in the form of a cone or wedge which improves the appearance of the device yanci facilitates, initially', the sharp outlining of the facial area to which the lipstick is to be applied.

Such conventional lipsticks, however, have the disadvantage that after a few applications of the stick, the shape of the tip thereof becomes wom away and distorted to such extent that it becomes extremely dimculty, if not impossible, for most users to obtain a clean sharp outlining of the edges of the area to which the cosmetic is being applied.

' In addition, th-e projecting bariof lipstick paste. or its projecting tip, frequently becomes broken oil, or bent over, and the projecting bar also ex poses a large side ,area which is apt to Soil the lingers or materials with which it comes in contact, -or to itself become soiled by foreign matter, with consequent inconvenience to the user and shortening ofthe life of the lipstick.

Various `attempts have been made to overcome certain of these and other disadvantages of the conventiona1 lipstick, but in each instance `the problem of decreasing ability to sharply outline the area of application has failed of solution, and

in most instances this problem has actually` been.-

accentuated.

It is a principal object of the present invention to provide an improved lipstick or lipstick cartridge peculiarly adapted for the sharp outlining, throughout the life of the lipstick, of Athe facial -area of application thereof.

A further object of the invention resides inthe provision of a paste-confining sleeve for a lipstick adapted to define and support the formation and continuous renewal of a working surface particularly adapted for the sharp outlining and read filling in of the area of application.

Further objects and advantages of the invention as will appear from the following description of preferred embodiments thereof, reside in the provision of improved features and combinations of lpar-ts, useful in them-selves, and contributing to the realization of the aforesaid objects. The invention comprises the arrangements and com- 2 l y binatlcns of parts hereinafter described and claimed.

In the accompanying drawings of preferred embodiments oi the invention:

Figs. 13 to 17 are details of modified forms of the invention, taken in the same manner as Fig. 5 with the exception of Fig. 14a which is a plan view of the form of Fig. 14;

Figs. 18 and 19 are comparative details in side elevation of two related forms of the invention.

As is shown in the aforesaid drawings, an important feature of the present invention resides in the provision of a paste-confining sleeve for contactingly embracing the lipstick material and A peculiarly shaped at its working end so that its working end walls define and support the formation thereat of a substantially straight self-supporting outwardly facing ridge in and extending crosswise of the exposed area of lipstick paste. Atter much research, I have found such form of ridge particularly adapted. if not essential, to the obtaining by most users of a sharp unblurred line at the facial edges of the lip area within which the lipstick is to be applied,

in the embodiments shown the working end of the aforesaid sleeve is obliquely truncated for a substantial part of its width, as viewed in side elevation (see Figs. 5, 7, and.12 to 19) to provide working end walls framing and defining -a first working Iarea. A facing outwardly at an angle to the longitudinal-axis of the sleeve. This oblique surface of truncation, and hen-cethe working area A provided thereby, is preferably planar or conveirly near-planar, as shown in Figs. 5, 7, 9 to 12, y14 to 16, 18, and 19, but may be concaved in part or in whole, as shown in Figs. 13 and 17, for example, and the term "plan-ar as herein applied to the areas and surfaces A and B is to be interpreted as meaning near-planar in this sense.

In the forms shown in Figs. 5, 9, 10, and 13 through 19 the working area A extends obliquely across more than halt of the s ide elevational width of the sleeve, which, as there employed has a symmetrical cross section. and in the form of Fig. 7, which has two general working areas each extends obliquely across substantially half of the side elevational width of the sleeve.

Thus in all the embodiments shown, the obliquely positioned working area A is relieved at its most advanced edg'e by a second working area B positioned at a relieving angle relative to the rst working area, so as to provide at the juncture of the two working areas, or planes, the free ridge C of lipstick material in and extending crosswise of the surface ABC exposed at the working end of the paste-confining tube, or sleeve. As will be clear from the illustrated embodiments, the juncture of the two working planes or areas A and B making up the working surface of the lipstick end is so located that the ridge C has linear extent rather than being in the nature of a point, for the purpose hereinafter described (see Figs. 3, 4, 6-8, 9, 10, and 11).

As is further apparent from a general consideration of the drawings, in the embodiments shown the walls of the sleeve adjacent the juncture of the two working planes, i. e., at their ridge deiining apices, are preferably rounded off to impart to the ridge C a slightly blunt or rounded contour, as is clearly shown in Figs. and 10, to facilitate the sharp outlining of the area to which the lipstick is to be applied.

In addition, in the several embodiments shown, the end walls of the tube or sleeve defining and having their end faces co-planar with the working surface ABC of the lipstick, preferably have their outer edges suitably rounded to promote smooth contact with the face and lips of the user.

The inner edges of these end walls are preferably smooth and square, or nearly square, although these edges may be slightly rounded, if desired.

While in the broader aspects ofthe present invention the ridge C may be located centrally in the working surface ABC or offset therein to suit individual preferences, in the preferred forms of my invention the ridge is oiIset from the central plane. This is4 desirable regardless of the diameter of the lipstick With lipsticks of relatively large diameter, the oil'setting of the ridge reduces its length compared to the maximum width of the lipstick, and facilitates the obtaining of a sharp-edged outlining stroke. It also serves I apices are slightly blunt, as is best shown Figs. 2 and 5. The tips 23 'and 23a thus define what might be called the gable ends of the blunted ridge C (Figs. 3 and 4) which lies in and extends crosswise of the working surface ABC of the lipstick paste 25 when the tube is fined with lipstick composition so that its working surface ABC is substantially ush or co-planar with the end walls 24', 24a of the tube 20. In this embodiment the low edges 2lb and 24o lying between theend walls 24, 24a, are also co-planar with the planes 2i and 22, respectively, and the rounded tips 23, 23a, have their surfaces generally parallel to the trace of intersection of these planes.

Otherwise expressed, in this embodiment the open working end of thecpaste-conning sleeve 20 is framed by end walls comprising two ridgedefining side portions 24,'. 24a and front and back portions 2lb and 24o, and the rounded o tips 23, 23a of the side portions 24, 24a are located at an elevation higher than that of a line connecting said front and back portions 2lb, 24o. Thus the lipstick paste 25 filling said tube at said working face and shaped in conformity therewith provides between 'said tips a laterally extending lip-outlining ridge C and working areas A and B extending between said ridge and said front and back portions 2lb and 24e.

In accordance with this invention suitable means is provided for extruding or advancing the filling of lipstick paste to the working surface ABC defined by the end walls 23, 24, 23a, 24a of the tube or sleeve 20 for consumption thereat. In my research, I have determined that while some reshaping or flowing of lipstick paste of normal consistency may be practiced without squeezing out the oil in the paste, with normal consistency paste excessivev4 extruding vpressures should be avoided. I have found, however, that without adoption of special paste it is possible to employ an extruding means such as that shown in Figs. 3 to 5, which comprises a threaded rod 26 having a relatively small diameter as compared to the internal diameter of the sleeve 2li, and embedded in the lipstick composition. When such threaded rod is employed, it is rotatably secured in the sleeve 20 and provided with a suitable rotating device. In the form shown, this is effected by providing the feed screw 26 with a shoulder 26a and knob or other turning device 2Gb engaging the opposite faces of a spider or bottom wall 21 to reduce the height of the surface B, and to thus aid in the use of this surface for outlining, particularly adjacent the corners ofthe mouth. In very slender forms of lipstick according to this invention the offsetting is also desirable, as this enlarges the working area A without requiring the planes of truncation to be so greatly inclined as to produce a ridge so sharp or feather-edged as to be subject to deleterious disintegration in the applying of the cosmetic.

Referring now to the respective embodiments shown in the drawings, in the form shown in Figs. 1 through 5, the paste-conning tube or sleeve 20 has a cylindrical cross section and has its working end truncated on a main working plane 2i (Fig. 5) and on a second working plane 22 (Fig. 5) arranged at a relieving angle to the rst working plane 2|. The extreme tips 23 and 23a of the working end walls 24 and 25a of the sleeve 2li are rounded off so that these tips or integral with or secured in the tube 20. vThus on turning of the device 2Gb the rod 26 is rotated, advancing the follower or plunger 28 with which it is threadedly engaged, and extruding the lipstick composition 25 with slight flow near the end of the rod to cause its upper body to advance uniformly to the position of use, at whiohposition the working surface ABC of the composition lies substantially flushwith the end walls 23, 24, etc., of the tube 20.

It is desirable during this extruding operation that practically no turning of the working surface ABC of the composition 25 occur relative to the tube, ,as it is desirable to maintain at all times the substantial alignment of the ridge with the apices 23, 23a, to insure a smooth and uniforml andere or spline 28a integral with or secured in-tube 2li and engaging in a slot formed in the edge of the L plug 28. E

A suitable housing, cap, or cover of any conventional or special form, as is generally Drovided in the art, may be employed with the present lipstick cartridge, a conventional form of cap being shown in dotted lines at 29, Fig. 3. While various individuals may follow their own preferences in the use of the lipstick of this invention, the preferred mode of use of the lipstick of Figs. 3 to4 5 is shown in Figs. 1 and 2. As indicated in Fig. 2, in the application of lipstick-it is desirable to rst outline the area of application, using a relatively narrow line D,

A- and to attempt to impart to that line a sharp,

clean-cut outer edge E. On the completion of such outlining the so defined area is lled in, the commencement of such lling in being indiV cated at F in Fig. 2.

In the preferred manner of performing this operation with the lipstick of Figs. 3-5, the lipdefining end Walls of the tube 20, a sharp, clean outer edge E is formed on the outline D. When the outlining is. completed, the filling in, as at F, is eiected. With but slight practice the user quickly acquires the habit, engendered by the construction of the device, of using both the areasA and B for the lling in operation, so that both are reduced in height and caused to dish below theetube end walls (the resiliency of the lips producing this effect) before the paste advancing 'means is operated to restore the surface ABC to substantially its initial level. By this sequence of applying steps the working surface ABC of the paste 25 receives an almost uniform height reduction, and on advance of the paste in the tube 20, is returned to substantially its initial ush or very slightly protruding relation to the working end walls of the tube.

During application of the areas D and F the lateral walls 24, 2da ofi-the tube-end smooth the paste upon the lips, rendering later blending with the nger or a brush practically unnecessary. When used with the levels .of the working areas A or B dished-in slightly below the end walls 2d, 24a, the lip is smoothed and the cosmetic uniformly applied, and these end walls A act to limit the thickness of the applied lipstick coating and to avoid local or general over-application.

.While I understand that I am not bound by the theory of operation which I conceive to account for the successful obtaining of a sharp edge E with my invention, this result is best obtained by employment of mutually relieving dit the applying stroke is commenced. -This I attribute tothree factors: (1) ythe small amount of paste material available at the edging region.

(2) the short period of contact of the material with the lip during a normal stroke of the lipstick, due to the narrowness of the edging tip,y (3) the presence of the scraping walls of the tube immediately adjacent and surrounding the edging region. i

However, when the working surface is relieved, as by further truncation on plane 22 (Fig.

5), this dilculty is overcome. Extremely slight relieving produces a marked improvement in the edging at E. but the best results are obtained when the relief is sufficient to produce a slightly rounded ridge C of'reasonable length. Such a length provides enough material at the ridge for at least one complete outlining of the edge of the lips without interruption for the feeding of more paste to the working surface. The precise length of the ridge C is somewhat dependent on ythe cross-section of the surface ABC, the ridge preferably being offset to provide different sized areas A and B to cooperate with the bluntness of the ridge to in effect give the ridge C different.

lengths at its two working edges. The provision of ridge C of substantial extent, and.` framed only at its gable ends, makes available a considerable quantity of unconflned lipstick material at the ridge, and, indeed, the paste forming the [applying area A or B seems in use to ilow slightly at the ridge edge of the skin-contacting area and to there extrude a tiny line of paste to form the edge E just far enough beyond the line of facial contact'of tips 23-23a to avoid its being scraped or thinned down by these tips, so that the extreme edge E of the outlining area D on close examination seems frequently to be 4actually thickened and sharpened, compared to portions of the area D removed from that edge. Whether these are the proper or only reasons why the improved outlining is obtained by my device, and

'whether anyone of them is more important than the others, I do not undertake to say, but they are reasons believed to account for the improved tially half of the tube diameter to their zone of planes or areas and with such planes positioned juncture, where the tips 33, 33a are rounded on to define a blunted 90 ridge C. The lateral end Walls 3d, 34a and the tip ends, as ,in the embodiment of Figs. 1-5, are co-planar with the adiacent portionsoi theworking surface ABC of the lipstick paste 35, and may be smoothed and rounded as in that embodiment. The paste advancing means 36 in this embodiment is shown in the form of a conventional spring-spider cup adapted to be advanced by insertion of a, pusher member (as the tip of a pencil, nail file', or matchstick) throughithe open bottom 3'! of tube 3u.

In use the lipstick material adjacent the working surface ABC becomes contactingly engaged'by the surrounding walls of the tube 3U. A conven- 75 tional cap 39 may also be provided'. Since the -ridge C lies at the diameter of tube Il, this form L provides a maximum length of ridge for a given Y Y diameter cylindrical tube. l. -A

The preferred mode of application with this connection with Figs. 1 and 2, except that'in'this case the areas A and B/,being of equal extent and form willbe employed indiscriminately for lining and filling in, whereas in the form of Figs. 3-'5 the. larger area A is usually employed for filling As will be noted from Figs. 1.--5 and 6 8, the

mutually relieving planes in`these embodiments are each rather steeply inclined to the longitudinal axis of` the lipstick, this arrangement beingv preferred as it provides for maximum visibility of the edge E when a mirror is employed during mented extent.

In the embodiment of Figs. 9 and 10, the tube 40 is of rectangular or square cross section, and' the mutually relieving working planes 6| and I2 are disposed to define the ridge C parallel to two opposed sides of the rectangle, and in spaced relation thereto. Otherwise this form is similar to that of Figs.15. A

Y In the form of Figs. ll-12 the tubebil is of square cross section. The mutually relieving planes 5l and 52 are steeply inclined. This increases the visibility of the ridge C and augments the areas A and B. The planes 5i and 52 in this form are disposed to position the tips 53, 53a and hence the blunted ridge C near the back wall 54o of the tube, where it will be relatively short for the diagonal'width of tube employed. The Working areas A and B in thisform, like those in Figs. 1 5, are of unequal extent and employed selectively, as desired. A o Further, in this form the planes oi truncation are each convexed, and the tips 53a are slightly rounded. Thus by tilting the axis of the lipstick upwardly and downwardly more: or less, as viewed in Fig. 2, narrower or. wider areas of the applying 4.'.

surfaces A or B may b'e brought into play, and a slight shifting of the contact edge adjacent the ridge may be effected.

In forms of the invention using tubes of nonclrcular cross section (see Figs, 9-12 and 14- 50 14a), such cross section alone prevents rotation of the working surface ABC relative to the end walls of the tube dening and framing the same.

The form of Fig. 13 may employ a tube 6l) of any desired cross sectional shape having a substantial width at the line of the ridge C, and in this case the lateral end walls defining the Working area A are concaved to more nearly conforni to the contour of the lip, while the lateral end walls defining the working area B are convexed m,

to narrow the line made whenV this area is used for edging (see D, Fig. 2). I n this form the ridge `C is but slightly blunted.

The embodiment of Figs. 14 and 14a employs a tube lil'formed to effect a minor re-shaping o5 the oil therefrom. In this embodiment the plane of the lateral walls' defining the working area' A is rather steeply inclined to augment the oblique area. thereof, and the relieving plane of the lateral walls defining the working area B is normal to the longitudinal axislof the tube 10. The remaining or back wall adjacent area B in this form,is flattened, as shown, to produce a straight wall section llc paraliellng the ridge C and more proximate thereto than Vthe projection of the embodiment is the same as that described in s cylindrical section of the tube would be. This a facilitates narrowing of the line D (liig. 2) and in addition increases the visibility of the ridge area C when the varea A is being applied to the flips.

In` the form of Flg.- 15 the lateral end walls of the tube Bil defining the working area A are steeply inclined to augment the extent thereof, the

lateral` walls defining the ridge C are bluntly rounded, and those deilning the areaB are concaved to more closely conform this working area to the contour of the lips, and enable a very line line D to be attained at the corners of the mouth by contact of Just the edge of B adjacent the Y ridge C in working thereat. The tube 80 may lining, and also provides areas A and/or B of aug- 20 be of any desired cross sectional area providing a substantial ridge length.

In the forms of Figs. 16 and 17 the end walls dening the working areas A aare steeply inclined to augment these areas, being straight in the form of Fig. 16V and concaved in that of Fig. 17. In these embodiments the end walls defining the relieving areas B are inclined downwardly from the rear edges e to the ridge C, but at a markedly less steep angle than the wallsdening the areas A, to provide the ridge. The ridge is obtuse in each form and more highly rounded in the formV of Fig. 17. In the form of Fig. 16 the tube is shown as comprising a thin metal body portion 90 in which is firmly mounted a plastic tip section 90a, and in Fig. 17 the tube is shown as of all plastic construction, but in these forms as well as the forms of Figs. 1-15, 18, and 19, I contemplate employment of any suitable material.

It will be understood that the present invention is not limited in this regard, and that various materials, for example, metal, plastic, fiber. or composite tube material, may be employed.

As above mentioned, in describing the working surface ABC, or the working areas A and B and their bounding walls as planar" herein, I contemplate the planes, asti and 82, Figs. 18 and 19, to which these surfaces, areas, or walls generally conform, as distinguished from any thought of defining purely i'lat surfaces. Thus in Figs. 18 and 19, the working areas A and B and the lateral end walls defining them are both preferred forms included in this use of the term planar," though the working areas A and B in Fig. 1B are-substantially fiat, and those in Fig. 19 are substantially convexed, in the direction normal to the length of the ridge C.

From the foregoing description of preferred Y embodiments, it will be apparent that various combinations of flat, convexed and concaved surfaces A and B, arranged to be mutually relieving and ridge forming, may be employed, and that the fundamental features of the invention in its broader aspects maybe embodied in forms other than those. selected to illustrate the same.
